On a hot summer day, London is a fantastic city for outdoor swimming. Take a refreshing dip in one of the city's outdoor swimming pools or lidos while enjoying some time spent outdoors in London. And, even if the weather isn't so great, some of the pools and lidos are heated for use on cooler days.

What is the difference between a lido and a swimming pool?
A swimming pool can be located indoors or outdoors, while a lido is always found outdoors. A lido, like many of those on the list here, often has additional space for sunbathing, changing and grabbing a snack.
